Abstract
The utility model relates to a shape-correction device for the non-uniform axial deformation of the protecting ring of a turbine generator in the hydraulic dilation and aggrandizement. A public die is used to add a soft metal backing ring at the contact point of a plunger tip and a protecting ring, and the backing ring is arranged the end part of the plunger tip and is positioned at the internal diameter point near the bending and straight intersection of the generatrix in the outside of the protecting ring. The section shape of the backing ring is a triangle, U-shaped and L-shaped. The utility model has the advantages of simple and economical, the shape-correction quality is good, and the internal stress of the protecting ring is small.
Description
The utility model belongs to metal processing class, is applicable to the generator guard ring of all size, dilate in the reinforcement at hydraulic pressure, and when the generation axial deformation is inhomogeneous, the device that carries out alignment.
Russian Patent (SU 287659) discloses a kind of " strengthening the device of circular material blank ".As everyone knows, the device of retaining ring hydraulic pressure expanding and reinforcing is between a pair of upper and lower conical punch on the same axis, is inserted in workpiece, and injects transmission medium in cavity, when exerting pressure, can form the device that high pressure sealing makes the workpiece bulging.When dilating in order to eliminate ring, along the inhomogeneous deformation of short transverse, prior art be before bulging place oblique iron chains ring between drift and workpiece and on the external diameter at ring two ends lock ring support ring band, pump pressure bulging then, this device more complicated.Prior art is conceived to prevent that retaining ring from producing axial inhomogeneous deformation before the bulging that because the restriction and the misoperation of working condition, in the bulging process, retaining ring usually can produce recessed waist shape defective, and becomes waste product.Produced the inhomogeneous deformation of edge height when retaining ring after, prior art can't be carried out alignment.
The purpose of this utility model is that prior art is improved, and a kind of simple device is provided, and after coming generator guard ring produced the uneven distortion of horn mouth in hydraulic pressure expanding and reinforcing, carries out alignment, makes it waste product and brings back to life.
The utility model is to utilize existing expanding die to place the soft metal gasket ring in the end of drift, and gasket ring is positioned near the inner radius the outer right and wrong interface point of bus of retaining ring, and its cross sectional shape can be triangle, U-shaped, L shaped.The soft metal can be the plasticity gasket ring less than retaining ring intensity.School shape drift can be made in addition, but cone angle must be greater than angle of friction, and guaranteeing can self-locking.
Device of the present utility model such as Fig. 1.Below in conjunction with accompanying drawing the utility model is described in detail.
Conical upper punch (1) and conical low punch (2) are enclosed within the top end of guide pillar (3) opposite to each other, upper punch bears the symmetrical load of forcing press by ball ring (4), low punch is contained on the walking on stage of forcing press, workpiece (5) is enclosed between the upper and lower drift, it is to have produced the retaining ring of inhomogeneous deformation through behind the bulging along short transverse, is recessed waist shape.Near outside being positioned at retaining ring the right and wrong intersection point of bus inner radius, placing a cross sectional shape is L shaped No. 20 steel gasket rings (6), drift is contacted with workpiece by gasket ring, inject water in the annular spaces that between workpiece and guide pillar, forms, when forcing press is exerted pressure, upper and lower drift is drawn close in opposite directions, water forms the high pressure local loading, make the outer bus of retaining ring by Qu Bianzhi, after retaining ring and drift are drawn close, lift drift and add entry again and add rolled-up stock again and produce release after the homogeneous deformation in a small amount, the retaining ring shaping finishes.
The utility model is easy, economy, school shape quality are good, and the retaining ring internal stress is little, and can double as the bulging device of retaining ring.
The drawing explanation:
The conical low punch of 1---conical upper punch 2---
3---subtracting power guide pillar 4---anchor ring pad
5---by the product 6 of school shape---the soft metal gasket ring
7---forcing press is walked table top
Claims (4)
1, a kind of corrector of hydraulically intensified generator guard ring, be that a pair of conical punch is up and down arranged on same axis, upper punch links to each other by the moved cross beam of ball ring and forcing press, low punch is contained on the walking on stage of forcing press, workpiece is enclosed within, between low punch, inject transmission medium in the cavity that between drift and workpiece, forms, place the metal gasket ring at drift and workpiece contact position, it is characterized in that the metal gasket ring that described drift and workpiece contact position place places nose of punch, be positioned near the inner radius of the outer right and wrong intersection point of bus of retaining ring, its cross sectional shape can be triangle, U-shaped, L shaped.
2,, it is characterized in that described metal gasket ring can be the plastic metal less than retaining ring intensity according to the corrector of the described hydraulically intensified generator guard ring of claim 1.
3, according to the corrector of claim 1,2 described hydraulically intensified generator guard rings, it is characterized in that described plastic metal gasket ring, material can be No. 20 steel.
4, according to the corrector of the described hydraulically intensified generator guard ring of claim 1, it is characterized in that described drift can make in addition, cone angle is greater than angle of friction.
